is a community creative activity of "Neighborhood Food Fair, Happy Home Festival" with the theme of food sharing, which is planned and hosted by the "Eat at Home" app. "Eating at home" is a social platform integrating home cooking service and food sharing. It aims to integrate idle resources in the community, build a platform for people who don't have time (won't, don't want to) cook but care about their health and those who have leisure time and have cooking skills to find each other nearby, and create income channels for people who have leisure time while solving the problem of "eating at home", so as to embody and practice "neighborhood sharing, mutual help and mutual assistance"
